I do not think so, not at this time, sorry. It is far too intrusive
change, and patch is obviously incomplete, in particular, it does not
touch lease renewal at all. I also think we should keep net_bootp doing
what it does now, and provide new net_dhcp, not replacing exiting
functionality.
What we do need is to fix manual to not claim we are doing DHCP right now.
